Bioaugmentation with marine sediment-derived consortia in mesophilic anaerobic digestion under high ammonium or salinity condition. sludge metagenome

Bioaugmentation with marine sediment-derived microbial consortia (MSC), which can tolerate high concentrations of both ammonium and NaCl, was successfully applied to enhance methane production under inhibitory levels of ammonium and NaCl. Microbial communities before and after bioaugmentation were analyzed to elucidate the mechanisms of mitigating the inhibitory effects of ammonium and salinity on methane production.
